10 cze 2024 · The binomial theorem is a formula for expanding binomial expressions of the form (x + y) n, where ‘x’ and ‘y’ are real numbers and n is a positive integer. The simplest binomial expression x + y with two unlike terms, ‘x’ and ‘y’, has its exponent 0, which gives a value of 1. (x + y) 0 = 1.
Learn the definition, formula and examples of the binomial theorem, which is a formula for expanding polynomials. See how to use exponents, coefficients, Pascal's triangle and sigma notation to simplify calculations.
The Binomial Theorem allows us to expand binomials without multiplying. See Example \(\PageIndex{2}\). We can find a given term of a binomial expansion without fully expanding the binomial.
Examples. Here are the first few cases of the binomial theorem: In general, for the expansion of (x + y)n on the right side in the n th row (numbered so that the top row is the 0th row): the exponents of x in the terms are n, n − 1, ..., 2, 1, 0 (the last term implicitly contains x0 = 1);
The binomial theorem provides a method for expanding binomials raised to powers without directly multiplying each factor: (x + y)n = n ∑ k = 0(n k)xn − kyk. Use Pascal’s triangle to quickly determine the binomial coefficients. Exercise 9.4.3. Evaluate.
Apply the Binomial Theorem. A polynomial with two terms is called a binomial. We have already learned to multiply binomials and to raise binomials to powers, but raising a binomial to a high power can be tedious and time-consuming.
